Installation & Maintenance Instructions of air valve

Installation Instructions: 

1.  The air valve must be installed vertically, the internal float must be in a vertical state, so as not to affect the exhaust;

2.  When installing the exhaust valve, it is best to install it together with the gate valve, so that when the exhaust valve needs to be removed for maintenance, it can ensure that the system is airtight and water does not flow out;

3.  Exhaust valves are generally installed in the pipelines where the system is easy to collect gas, such as the highest point of the system and the highest point of a section of pipeline, which is conducive to smooth exhaust. When there is gas overflow in the system, the gas will climb up the pipeline and eventually gather at the highest point of the system. The exhaust valve is generally installed at the highest point of the system. When the gas enters the exhaust valve cavity, it gathers at the highest point of the exhaust valve. On the upper part, as the gas in the valve increases, the pressure rises. When the gas pressure is greater than the system pressure, the gas will drop the water level in the cavity, and the float will drop with the water level, opening the exhaust port.

                                                         

          

Maintenance Instructions:

When the exhaust valve is in use, if you find that the exhaust leaks due to dirt jamming, please remove the exhaust valve for cleaning, and then reinstall it after cleaning.
